本文实例讲述了php实现mysql事务处理的方法。分享给大家供大家参考。具体分析如下:

要实现本功能的条件是环境 mysql 5.2 /php 5 支持事务的table 类型,需要InnoDB,有了这些条件你就可以做上面的实现了,这个事物回滚操作是大项目经常用到的,像银行,电子商务等都会用到,有需要的朋友可以参考一下.

近期项目软件升级到支持事务处理,做个示例供大家学习参考.

环境 mysql 5.2 /php 5

支持事务的table 类型 需要InnoDB

php mysql 事务处理实现程序代码如下:

复制代码 代码如下:
$LinkID =mysql_connect('localhost:3307','root',*******);
mysql_select_db('web_his',$LinkID);
mysql_query("set names utf8");
 
/* 创建事务 */
mysql_query('START TRANSACTION') or exit(mysql_error());
$ssql1="insert into pf_item values('22','我们','30')";  //执行sql 1
if(!mysql_query($ssql1)){
   echo $ssql1.mysql_errno().":".mysql_error()."
";
   mysql_query('ROLLBACK') or exit(mysql_error());//判断当执行失败时回滚
   exit;
}
$ssql1="insert into pf_item values('21','hell','10')";  //执行sql 2
if(!mysql_query($ssql1)){
  echo $ssql1.mysql_errno().":".mysql_error()."
";
     mysql_query('ROLLBACK') or exit(mysql_error());//判断当执行失败时回滚
   exit;
}
 
mysql_query('COMMIT') or exit(mysql_error());//执行事务
 
mysql_close($LinkID);
?>
